I am working with Knockout
support and now creating tree structured UI
component. Here i will create the elements dynamically and there i want to bind the data to newly created elements.
Please check with the below code
<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
<script type="text/html" id="tree">
<li menuid="data bind with attr binding">
<span> </span>
<span><a href="#" name="endnode"></span>
<ul data-bind="template: { name: 'tree', foreach: childNodes }">
</ul>
</li>
below is my script
var viewModel = {
Mytree: ko.observable({
childNodes: [
{
id: 1,name:"node1",
childNodes: [ {id: 2, name:"node2", childNodes: [{id: 3,name:"node3", childNodes: [] }] } ]
},
{
id: 4,name:"node4",
childNodes: [ {id: 5,name:"node5", childNodes: [] } ]
}
]
})
};
ko.applyBindings(new viewModel.Mytree());
Now i want to append the bindable
node names to to tree like below:
<span><a href="#" name="endnode" data-bind:"text:childNodes.name"/></span>
<ul data-bind="template: { name: 'tree', foreach: childNodes }">
Can you please any one suggest me to achieve this
If you pass it the view model (you can use the $root syntax for this) you can just use "name" in the binding. The context will change as it goes down the tree ... there's a couple of other bits wrong - for one it's data-bind= (equals, not colon)
Try this template ...
<script type="text/html" id="tree">
<li menuid="data bind with attr binding">
<span> </span>
<a href="#" data-bind="text: name"></a>
<ul data-bind="template: { name: 'tree', foreach: childNodes }" />
</li>
</script>
and use this to kick things off (note $root)
<ul data-bind="template: { name: 'tree', data: $root }" />
this will give you ...
